Drivetrain for BMW 6 Serie 640 I F12
The BMW 6 Serie 640 I F12 represents a unique blend of luxurious comfort and sporting performance. For this powerful machine to deliver its full potential, a drivetrain in peak condition is vital. Power transmission is at the heart of the car's dynamics, and every component from the gearbox to the wheel hubs plays a critical role. When maintaining your BMW 6 Serie, it is essential to choose components engineered to handle the torque and demanding stresses generated by the 640i engine. A soundly functioning drivetrain not only guarantees a smooth and vibration-free ride, but is also fundamental to the vehicle's safety and long-term value preservation.
Investing in the correct parts for your BMW 6 Serie 640 I F12 ensures you retain that original driving feel. Worn components in the power transmission can gradually degrade responsiveness and place unnecessary stress on other mechanical systems. We focus on providing parts that match the technical specifications of the F12 model precisely, ensuring every spare part works in harmony with the car's other systems. Whether cruising on the motorway or tackling winding country lanes, an intact drivetrain is the key to the ultimate driving experience BMW is renowned for.
How the drivetrain is engineered on the BMW 6 Serie 640 I F12
The drivetrain on a BMW 6 Serie 640 I F12 is a sophisticated assembly optimised for efficient power delivery. The system begins at the longitudinal engine, which sends power through the gearbox to the propeller shaft. The prop shaft acts as the central link transporting torque to the rear of the vehicle. At the rear axle, power is distributed via the differential to the drive shafts, where constant velocity joints allow the wheels to move up and down with the suspension while rotating at high speed. This architecture demands extreme precision at every joint to minimise energy losses and unwanted vibrations.
For the F12 model, which often runs as an elegant convertible, quiet running and freedom from vibration are particularly vital. Every part in the drivetrain is balanced to eliminate resonance that could otherwise transmit into the chassis. The CV joints are packed with specialised grease and shielded by CV boots to endure the variable angles and temperatures encountered during driving. Understanding this complex configuration is essential when choosing replacement car parts, as even minor deviations in dimensions or materials can compromise the balance and handling of the entire vehicle.
Common faults and symptoms
Several warning signs suggest that the drivetrain on your BMW 6 Serie 640 I F12 requires inspection. One classic symptom of a worn outer CV joint is a rhythmic clicking or knocking noise audible when making sharp turns at low speed. This noise occurs when the balls in the joint no longer run smoothly in their tracks due to wear or lack of lubrication. If you detect vibrations through the steering wheel or seat during acceleration, it may instead indicate an imbalance or wear in the propeller shaft or its universal joints.
Another common symptom is vibration arising at specific speed ranges. This can frequently be traced back to the prop shaft or its centre bearing, where slight play can create substantial disturbance in power delivery. It is also crucial to inspect for grease leakage around the CV boots; if a boot splits, lubrication is quickly lost and grit penetrates, causing accelerated wear. By staying alert to these early signs, you can resolve issues before they result in more extensive and costly repairs to your BMW.
Common replacement parts for the BMW 6 Serie 640 I F12
When maintaining the power transmission on a BMW 6 Serie 640 I F12, two components primarily take centre stage. The outer CV joint is one of the most heavily stressed parts because it must manage both torque transmission and substantial steering angles. Due to the high torque of the 640i engine, these joints face significant mechanical strain over time. Replacing a worn joint with a new, precision-fit unit is essential to restore smooth, quiet operation.
The propeller shaft is another core component that may require attention, particularly on vehicles with high mileage or those driven hard. A defective prop shaft can cause vibrations that are not only irritating but also harmful to the gearbox and differential bearings. We supply high-quality propeller shafts that are balanced and ready for installation. By choosing parts designed specifically for the BMW 6 Serie 640 I F12, you ensure your car maintains its technical integrity and benefits from a lasting repair.

Frequently asked questions about drivetrain parts for BMW 6 Series 640 i F12
What are the most common signs of a failing CV joint on my BMW 640i?
The most common symptoms are a clicking or knocking noise when taking sharp turns, along with vibrations under acceleration. If you notice grease splattered on the inside of the wheel, it could indicate a split CV boot, which rapidly leads to severe CV joint wear.
Does the propeller shaft fit all BMW 6 Series 640 i F12 models?
Propeller shafts can vary depending on whether the car has rear-wheel drive or xDrive, as well as the specific gearbox fitted. Always select your vehicle's exact make, model and engine to ensure you get the correct prop shaft for your specific F12 configuration.
Can I replace just the outer CV joint, or must the entire drive shaft be replaced?
On the BMW 6 Series 640 i F12, it is often possible to replace only the outer CV joint if the rest of the shaft remains in good condition. This is a cost-effective solution that restores proper function without needing to replace the complete assembly.
Why is my BMW 6 Series 640 i F12 vibrating at higher speeds?
Vibrations at higher speeds can often be traced back to an unbalanced propeller shaft or wear in its joints and centre bearing. It is important to inspect these components promptly to avoid consequential damage to the differential and gearbox.
Do you offer a fitment guarantee on BMW drivetrain parts?
Yes, we offer a fitment guarantee when you choose parts tailored to your specific make, model and engine. This ensures that the components you order will be technically correct for your BMW 6 Series 640 i F12.
